Abstract
An image forming apparatus includes an image forming unit, a fixing device, and a control circuit. The control circuit acquires a selection signal indicating which mode is selected from among options.

The control circuit sets a different standby temperature in accordance with the mode indicated by the selection signal, and controls a temperature of the fixing device to be the standby temperature, in a standby state before an operation start reception.
